Here you go, saved you a couple of seconds.

Movement Speed Formula
(Base Movement Speed + Flat MS Bonus) * (1 + Sum of % affecting MS)
Where:
Base Movement Speed: Is the starting MS of any hero .
Flat MS Bonus: Is the Movespeed Bonus from any kind of Boots (Only the one that provides more MS will work) + the bonus MS from Euls
Sum of % affecting MS: Is the addition of any % incresing or decreasing buffs.

Example


Darkterror (300 Base MS) with Boots, Eul's and under the effect of Degen Aura Lvl 4 (28% slow) and Empowering Haste Level 1 (6% MS increase)
TotalMS= (300+55+25)*(1-0.28+0.06)
TotalMS=296.4

I read the mech page, and i wanna ensure that my understanding is right.

When a hero carries more than one type of boots, he will recieve the ms bonus of boots that give the highest bonus. How the boots are arranged in the inventory is irrelevant.

Aye?

How isn't that clear enough?

^Maybe he didn't mean that it's not clear, he just wants to make sure...
